Most importantly, the asteroid will zip past safely and continue its happy path.
If a year full of exciting near asteroids approaches, 2020 SW will be very cozy. It is expected to come within about 27,000 kilometers of the earth. It is closer than TV satellites usually orbit.
While, there is no need to worry about the last meeting. For comparison, earlier this year and arrived within about 7,000 kilometers of our planet.
Asteroid 2020 SW is quite nice and measures somewhere between 14 feet (4.4 meters) and 32 feet (9.9 meters) in diameter. The fact that we have a full week’s notice of its arrival is a good sign that our asteroid spotting systems are working well.
So tune in and say hello before 2020 SW says goodbye.
Next fun. That one will not signal doomsday either. Even if it enters our atmosphere, it will only decay.
